I just came across a show on TV promoting the use of renewable/alternative energy vehicles. The show is called
Coolfuel Roadtrip USA and although a lot of what they are presenting is only lightly covered and doesn't get too technical, (some just humorous) for someone just coming into RE, it's probably just the right. (not overwealming)
I also found there is a website for them at http://www.coolfuelroadtrip.com/
